# Frontier ## frontier, craygnu If you've set things up for this compiler, you should be able to source a load script similar to: ```bash source load_dev_polaris_0.6.0-alpha.1_frontier_craygnu_mpich.sh ``` Then, you can build the MPAS model with ```bash make [DEBUG=true] gnu-cray ``` ## frontier, craycray Similarly to `craygnu`, for `craycray`, if you've set things up right, sourcing the load scrip will look something like: ```bash source load_dev_polaris_0.6.0-alpha.1_frontier_craycray_mpich.sh ``` To build MPAS components, use: ```bash make [DEBUG=true] cray-cray ```
